  • INA303-Q1: delay function

    TI Thinks Resolved
    Part Number: INA303-Q1 Tool/software: Hi Expert, Regarding to the delay function of second comparator, I don't quite follow how delay work. For example, the delay time is set to 2ms, Vlimit2 is about 3.5V. If there have a 4V/1.5ms voltage pulse on…

  • INA303-Q1: Input voltage handling capabilities for the IC

    Part Number: INA303-Q1 Other Parts Discussed in Thread: INA303 Hi, I am trying to simulate INA303-Q1 for my application. The maximum input that can come across the positive and negative input of internal OPAMP is 33V continuous input. When I simulated…

  • INA303-Q1: Bidirectional overcurrent monitoring: ALERT polarity

    TI Thinks Resolved
    Part Number: INA303-Q1 Hi Experts, The alert pin of INA303-Q1 is active low, customer want active high, can they set lower threshold of ALERT1 than ALERT2? See pictures below, INA303-Q1 is configured in bi-directional monitoring mode. Customer want the…
